感谢您的支持!我现在有工作代码来扫描所有文件夹,子文件夹和文件。只需解决一个问题:

我没有在初始根目录中获得文件,只有子文件夹。我还需要为这些文件调用FileInfo

如何解决此问题而又无需过多修改代码?

private void ScanFolder(String prefix, String path)
{
    try
    {
        string user = System.IO.File.GetAccessControl(path).GetOwner(typeof(System.Security.Principal.NTAccount)).ToString();
        DirectoryInfo di = new DirectoryInfo(path);

        foreach (var dir in new DirectoryInfo(path).GetDirectories("*", SearchOption.TopDirectoryOnly))
        {
            listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + dir.Name + " (" + dir.Name.Length.ToString() + ")   "); });

            foreach (FileInfo fileInfo in dir.GetFiles())
            {
                listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + fileInfo.Name + " (" + fileInfo.Name.Length.ToString() + ")   " + user + "   " + fileInfo.FullName + " (" + fileInfo.FullName.Length.ToString() + ")"); });
            }

            ScanFolder(prefix + "—", dir.FullName);
        }
    }
    catch
    {
        if (!this.IsDisposed)
        {
            listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add("Access Denied to : " + path); });
        }
    }
}

输出:

**文件应在此处**

到目前为止,您仅在根目录中查找目录。
您还想通过文件枚举:

private void ScanFolder(String prefix, String path)
{
    try
    {
        string user = System.IO.File.GetAccessControl(path).GetOwner(typeof(System.Security.Principal.NTAccount)).ToString();
        DirectoryInfo di = new DirectoryInfo(path);

        // Enumerate through the files here
        foreach (FileInfo fileInfo in di.GetFiles())
        {
            listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + fileInfo.Name + " (" + fileInfo.Name.Length.ToString() + ")   " + user + "   " + fileInfo.FullName + " (" + fileInfo.FullName.Length.ToString() + ")"); });
        }
        // ----

        // You can also use the DirectoryInfo you created earlier here
        foreach (var dir in new di.GetDirectories("*", SearchOption.TopDirectoryOnly))
        {
            listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + dir.Name + " (" + dir.Name.Length.ToString() + ")   "); });

            foreach (FileInfo fileInfo in dir.GetFiles())
            {
                listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add(prefix + fileInfo.Name + " (" + fileInfo.Name.Length.ToString() + ")   " + user + "   " + fileInfo.FullName + " (" + fileInfo.FullName.Length.ToString() + ")"); });
            }

            ScanFolder(prefix + "—", dir.FullName);
        }
    }
    catch
    {
        if (!this.IsDisposed)
        {
            listBox1.Invoke((MethodInvoker)delegate { listBox1.Items.Add("Access Denied to : " + path); });
        }
    }
}
